1 Claim. (01. 16-153) The invention relates to doors and more partively flat steel plate having notches I8 at one ticularly to automatically swinging doors that edge and a U-shaped groove [9 along this edge may be used in conjunction with a conveyor to for receiving a hinge rod 2!] which is secured in close an entrance to material carried on said consaid groove by welding or brazing said rod to said 5 veyor except when the material is passing through door. The upper end of the rod 20 projects 5 this entrance. through an opening 2| in a hinge member 22 One object of the invention is to provide a selfwhich is in the form of a metal angle member closing door structure that will swing to closed which may be welded onto a stop member 23. position in either direction and will be held in i The stop member 23 is in the form of a steel 1 engagement with a door stop in its closed posichannel member having its upper leg 24 detach-- tion. ably secured to the top jamb member M by bolts A further object of the invention is to provide 25 and its lower leg 25 acting as a stop for the a self-closing door having a hinge provided with door, said member 23 being reversible to present a cam member adjustable to bring the door the edge of the leg 26 to either side of the door, so

When, as noted the same. above, the conveyor is not in use, the entrance In Figs. 1 to 3, inclusive, a double door form of provided by the doors may be shut off by the the invention is shown. Each door I1 is a relapanel l6 inserted in the grooves I5. 55

In some instances, a single door structure such as the door 31 indicated in Fig. 11 may be used, this door having a hinge mounting similar to one of the double doors and similarly associated with a stop member similar to the first construction.

I desire it to be understood that this invention is not to be limited to any particular form or arrangement of parts except in so far as such limitations are included in the claim.

What I claim as my invention is:

A door hinge structure comprising a pair of cooperative cam hinge members and a rod, one of said hinge members adapted to be secured to the door jamb and the other of said cam members lengthwise adjustably threadedly mounted on said rod, said rod adapted to be fixed to the door.
